[cost\_intel] Using frontier models for code explanation, summarization, and documentation generation

Route code explanation/summarization to Flash/Haiku; reserve frontier models strictly for novel code generation where algorithmic complexity is high.

Journey Context:
Smaller models are exceptionally good at reading code and summarizing it because the 'answer' is fully contained in the prompt context. Quality drop is <5% for summarization. However, for generating complex algorithms \(e.g., writing a red-black tree from scratch\), smaller models exhibit a severe quality drop \(30%\+\), outputting suboptimal O\(n^2\) logic or hallucinating standard library functions. Cost diff: 10x-20x.
